This invention relates to fountain dividers as employed in connection with the ink feeding fountain on printing presses and in particularto a pad member employed `in connection withv a divider to partition the fountain so that inks of various colors may beused and fed to a fountain roller and sent `to a ductor roller without the necessity ofncutting the ductor roller.

A particular' object of 'my invention is to providea combination pad and strip which is so constructed that when it is used in connection with a dividing partition in an ink fountain, it will effectively prevent passage of ink Yfrom one side of the partition or divider to the other sideand will maintain on Vthe fountain roller in connection with which the pad is employed7 zones which are free of ink thus maintaining on the fountain roller clear spaces between the zones of colored inks.

In the present use of dividers in fountains p of the'character referred to7 paper is femployed for a stufhng orpad beneath the edgesV er is kept clean between the Zones of colored s inks and .my device may be employed with a saving of time and labor inasmuch as it is alreadyprepared and can be plaeedin position effectively and quickly.,

Another object of my invention -is to provide an adjustable divider which is used in connection with the pad and is arranged to jam the same against the fountain roller` so that a lealproof partition is provided at spaced points'along the fountain roller for the accommodation of various colors of'ink. I have also provided in connection with the divider, either of an adjustable typeor of .the

present fixed type, as employeh a rocker which when the divider is secured to the fountain, tends to throw the forward edge of the divider down `and Vinto the corner of the fountain where it meetsnthe fountain roller with the result that a clearly defined, clean zone between' the 'various colored inks employed on thefountain roller Vis obtained.

Chan ges and variationsmay be made in the construction shown and described without departing-from the principles of the inven-` tion or sac-ricing its chiefadvantages; hence such invention is not to be confined vto the structures shownin theacooinpanying drawing; in which7 i Figure l'is a yplan Avie'w'of'the strip portion of my pad `and strip.constructionshowe Ying the formationof the tongue which `is ar; ranged to fit into the pad.

Referring to the drawing in4 detail, `5 in- Vdicates.` a strip consisting of binder' 6 vof any material suchr vas buckram, for instance, y interposed between strips'of Yfelt. 7.Y The' strip at one end is out to provide a tongue Swhich is arranged to lit into the tongue bore 9` extending transversely through thefpad 10.

This pad is constructed of two of the strips 5 cemented together as at 11 and consistingy Lilo ' divider to the other.

of the binder .6 interposed between the layers of felt v7. rIhis pad 10 is arranged to have cemented in theopening 9 thereof previously referred to, the tong-ue 8 of the strip 5v and when this cementing as at 12 is accomplished, it forms at the lower end of the'pad 10, a substantially firm point or apex, the lower end of the pad 10 being bevelled Vas at 13 so that the lpoint 14 fits into the corner formed by the junction of the fountain roller and the fountain blade, as will be hereinafter described. 'I`hesti'ip 5 and the pad 10, Vwhen vsecured together as described, constitute a unitary separator pad, as it will be hereinafter referred to, which isl arranged to be used in connection with they divider 15 of an inli` fountain construction as commonly employed in connection with the fountain roller 16 of vprintiiig presses, it being understood that the ink is fed out ofthe fountain trough to a fountain roller 16 from which it is taken by a ductor roller ,17.l c i The usual. link fountain consists of the side or end walls 18 join-ed by the longitudinal strips 19 and 20 which in turn, are secuied together by the bottom rib 21, anynuniber of Athese ribs being employed depending upon the length of the fountain. In order Vto feed to the fountain roller, a nui ibcr of different colors of ink,it -is necessaryfto divide the fountain itself by placing dividers or partitions therein to form individual ink troughs but heretofore, difficulty has been encountered in keeping the inks separate and keeping them from leaking from one Ycompartment into another and also in keeping'the ink separate not only on the fountain roller but also on the ductor roller and to this end, I have made the pad up as hereinbefore described whichV is posi-tioiied so that the pad portion 10 rests against .the fountain roller while the strip portion 5 rests on the fountain blade 23, which in turnrests on the strips 19, 2O and on the bottom ribs 21 to form a bottom for the ink fountain, the forward end of the blade where it is slihtly spaced from the mountain roller, being adjustably positioned through the medium of a set screw 24 so that the feed ofink is controlled tothe -fountain roller.

This divider 15 is of substantially triangular formation and constitutes a compartment wall. It is .grooved at its forward end as at 25 and along its lower end as at 26 so that the edges thereof bite into the fountain pad as illustrated in Figures 8 and 9 and thus `prevent leakage of the ink from one side of the The fountain pad is thoroughly oiled to act on the fountain roller as a continuous cleaning padl for the space Y between the Zones vof ink on said fountain 4 roller.

The divider 15 has a nose portion 27 which engages at the meeting point ofthe same' down into the corner formed by the `roller, an uninked zone which separates the various-colored inks and retains them so sep- Y place, thetightening of the screw29 throwing the nose 27 of the divider down into the corner to effectively compress the strip 5 and prevent leakage in said corner. The yoke 30 is provided with an extension 31 in my adjustable type of divider through which passes an adjusting screw 32, the extension 3l being positioned in a bore v33 formed in the divider and into one side of which opens the slot 34 in which a pin 35 carried by the extension 3l is positioned to prevent sidewise rocking` movement of the divider 15 when it is being adjusted. Operation of the adjusting screw 32 will force the divider 15 down into positionagainst the pad to elfectivelv ferm seal with the fountain roller.

An important feature of my inventionisV the use of the rocker and inorder te provide it onV existing dividers in present day use, I have illustrated the same in connection with Figures 10 to 12 inclusive in which illustrated a divider made in a single piece, as indicated by the numeral 33 and having` the fastening yoke 34 thereon with its set screw 35 through the medium of which the divider 33 is held in position. The divider 33 is pro,- vided with a bottom groove 36 and into this groove, I slide the rocker which consists of a semi-cylindrical piece 37, the overhanging edges of which 33, rest on the edges 39 bordering the slot 36 in the bottom of the divider7 the one side of the member 37 also resting on the divider at the end of the'slot 3G in that portion indicatedby the numeral 40. Secured to the cylindrical portion 37 is the block 41 which may be rectangular in shape and may be of a thickness to suit the 'depth of the slot so that the top of the block is flush with the bottomv of the divider, a thin one being lillustratedfin-Figures'10 `and 11 while the thicker type of block iseillustrated in Figure 12, it beingfunderstood that the slot 36 is more or less standard and it is simply necessarypto force'fittheblock is, position the slot 36 in the position illustrated in Figure 10 and the rocker will be in place to vengage the fountainpad orV separator pad so that the divider will be thrown down as explained in connection with the type of construction shown in Figure 6.` v Y It is evident therefore, that I have pi'o vided a pad of felt wliicliwill not only standV wear but` which will efectively'sliape itself tothe contour of the fountain roller andthe front edge of the divider and which elimi- .ates 'the necessity of using force to make itl conform to the shape, tliereby preventing theV bending or buckling ofthe fountain. blade and the improper feeding of the ink.'Y bfy improved pad also eliminates the cutting of the ductor roller because the fountain roller 'is colored inks and the cementing of the strip member into the pad portion gives'a-rela-- My pad can also be made in a single piece in any manner or out of any material desired.

My invention is not to be restricted to the precise details of construction shown since various changes and 4modifications may be made therein without departing from the scc-pe ofthe invention or sacrificing tlieadvantages derived from Vits use.
